从India供应商批发进口5-Sulpho Salicylic Acid — FOB条款

5-sulpho Salicylic Acid (2-Hydroxy-5-Sulfobenzoic Acid, C7H6O6S) is an industrial-grade sulfonated aromatic compound supplied by New Alliance Dye Chem Pvt. Ltd. from Mumbai, Maharashtra. The material is typically available in powder or crystal form with assay levels above 98%, and is traded in standard 25 kg drums or bulk bags for global distribution. This compound functions as a critical intermediate across pharmaceutical synthesis, dye manufacturing, water treatment formulations, corrosion inhibition, and plasticizer applications in construction. The sulfonic acid group at the 5-position of the salicylic acid ring imparts enhanced water solubility and reactivity compared to the parent acid, making it suitable for direct incorporation into aqueous formulations without intermediate solubilisation steps.

The material is manufactured through controlled sulfonation of salicylic acid, typically using oleum or sulfuric acid at regulated temperatures to achieve para-substitution at the 5-position while minimising ortho-byproduct formation. Standard industrial grades exhibit excellent solubility in water and polar organic solvents including ethanol and methanol, with typical pH values of 1-2 for saturated aqueous solutions at 25°C. The sulfonic acid moiety confers strong acidic properties and metal chelating capability, which underpins its utility as a corrosion inhibitor in boiler water treatment and cooling systems. Typical bulk density for the anhydrous powder falls in the range 0.6-0.8 g/cm³, with a melting point decomposition range of 120-140°C depending on hydration state and purity level.

Primary buyers include pharmaceutical manufacturers utilising the compound for synthesis of sulfonamide drugs and diagnostic reagents, dye houses producing acid dyes and direct dyes for textile applications, and water treatment chemical formulators. Construction chemical distributors also source this material for corrosion inhibitor packages and concrete plasticizer formulations. Importers should confirm packaging specifications, moisture content limits, and certificate of analysis availability directly with New Alliance Dye Chem Pvt. Ltd., as the listing does not specify these details. The supplier's location in Mumbai provides access to JNPT for sea freight export, though inland transport arrangements for factory collection should be clarified.

New Alliance Dye Chem Pvt. Ltd. is located at 2, Ramkrishna Niwas, Prarthana Samaj Road, Vile Parle (East), Mumbai 400057, Maharashtra, India. The supplier holds a harbour trust tier designation on the platform, though the response rate is recorded at 0.00% with an average response time of 0 hours, suggesting limited or no recent engagement through platform messaging channels. The company operates from a commercial address in the Vile Parle area of Mumbai, a district known for chemical trading and distribution activity rather than heavy manufacturing.

The listing presents New Alliance Dye Chem Pvt. Ltd. as a supplier of 5-sulpho Salicylic Acid for industrial applications, but does not disclose factory ownership, production capacity, warehouse facilities, export licence status, or years in operation. No certifications, quality management systems, or client references are stated. Importers should conduct independent due diligence on the company's manufacturing credentials, request a current certificate of analysis for specific batches, and verify regulatory compliance for pharmaceutical-grade applications if required. Direct contact through alternative channels may be advisable given the platform response metrics.
